The scientists are currently developing a burger which will be grown from 10,000 stem cells extracted from cattle, which are then left in the lab to multiply more than a billion times to produce muscle tissue similar to beef.

The product is called ‘in vitro’ meat.

"I don’t see any way you could rely on old-fashioned livestock in the coming decades.
In vitro meat will be the only choice left."- Mark Post, professor of physiology at Maastricht University
